Rain expands east Tuesday into Wednesday

The latest system is producing rain across western and northern Minnesota Tuesday morning. Those showers will expand east through the morning. Eastern Minnesota and the Twin Cities can anticipate scattered afternoon showers into the overnight.

A second surge of moisture Wednesday looks to remain mostly in Iowa but could clip far southeastern Minnesota.

Temperatures and dew points will be above normal. Highs Tuesday will be in the 60s, but many in central Minnesota will see highs in the 70s where we get a break from the rain Wednesday.

Cooler, sunnier Thursday and Friday

High pressure builds in for Thursday and Friday. That means clouds will decrease Thursday, making for a bright afternoon and lots of sun on Friday.
